    Species will tend to get more toxic if their food source is contaminated by these hazardous Pt metals emitted from VECs. This can potentiality harm other species, including humans if we eat these hazardous animals, such as fish. [34] Cisplatin is a platinum based drug used in therapy of human neoplasms.

    The ruthenium in PUREX raffinate can become oxidized to form volatile ruthenium tetroxide which forms a purple vapour above the surface of the aqueous liquor. The ruthenium tetroxide is very similar to osmium tetroxide; the ruthenium compound is a stronger oxidant which enables it to form deposits by reacting with other substances. In this way ...

  8. Toxic heavy metal - Wikipedia

    en.wikipedia.org/wiki/Toxic_heavy_metal

    In humans, heavy metal poisoning is generally treated by the administration of chelating agents. [71] These are chemical compounds, such as CaNa 2 EDTA (calcium disodium ethylenediaminetetraacetate) that convert heavy metals to chemically inert forms that can be excreted without further interaction with the body.
